Title
How do genes work?
DNA’s job requirements

DNA replication
Replication: prokaryotic vs eukaryotic
DNA extraction lab
Instructional Objectives
  • Students will be able to infer from the articles that DNA is responsible for storing, copying, and transmitting genetic information.
  • Students will list the main roles of DNA
    • Copying info
    • Storing info
    • Transmitting info
  • Students will identify the four bases within a DNA strand as well at other structural molecules.
  • Students will describe in their own words who
  • Students will be able to identify and replicate the double helix structure of DNA
  • Students will describe the DNA replication process in their own words
  • Students will be able to identify the location of DNA replication in prokaryotic and eukaryotic cells
  • Students will be able to identify where DNA replication takes place in prokaryotic and eukaryotic cells
  • Students will be able to identify eukaryotic DNA from prokaryotic DNA by looking at it’s structure.
  • Students will extract DNA from the cells of strawberries




Procedure
  • Students will work in groups of three to read the articles.
  • Students will work in their groups to identify which role of DNA their articles discuss.
  • Groups will later disperse to other groups to teach them about their studied scientist.
  • Students will pork in pairs to complete a DNA investigation that reviews the main pieces and part of a DNA strand.
  • I will review the process of DNA replication through a series of power point notes that introduce
  • DNA ligase
  • Semiconservative replication
  • DNA polymerase
  • DNA helicase
  • The direction of synthesis
    • Students construct a concept map of DNA replication in eukaryotic and prokaryotic cells
    • See teacher’s manual for textbook

  • Six individual articles:
  • 2 depicting Griffith’s experiments
  • 2 depicting Avery’s experiments
  • 2 depicting Hershey and Chase’s experiments
    • Computers

    • Power point notes on key terms and processes that occur during replication
    • Video animation on the DNA replication process

    • CMap tools
    • Computers
    • textbooks
    • Self sealing plastic freezer bags
    • Ripe strawberries
    • Detergent solution
    • 25-mL graduated cylinder
    • Cheesecloth
    • Funnel

Evaluation
  • Students will be graded on their accuracy in describing the role of DNA with evidence from the articles that they read.
  • Students will be evaluated on the completion of the investigation and on the accuracy and completion of their homework assignement
  • Students will write a paragraph in their own words describing the process of DNA replication
  • Students will be assessed on the extent that they cover DNA replication in eukaryotic and prokaryotic cells
  • Students will fill out a lab report
